I have a different point of view than most. This user defines information security policies, enforces security best practices, and also recommends the data to be hidden and protected. To use the predefined masking formats on a target database (other than the repository database), you must manually install the DM_FMTLIB package on that database. It is recommended that you purge this information for security reasons. Proceed through the wizard steps as you ordinarily would to clone a database. You can also increase the number of threads dedicated to the job and thus increase its resources. As with the Active Sessions Waiting pages, look for skewed activity for either Top SQL or Top Sessions. Optionally declare dependent columns not defined in the database but enforced by the applications. After masking, test all of your applications, reports, and business processes to ensure they are functional. You can use the transportable tablespaces feature to move a subset of an Oracle Database and plug it in to another Oracle Database, essentially moving tablespaces between the databases. Materialized views are schema objects that can be used to summarize, compute, replicate, and distribute data. All of these ISBN numbers are random in nature. Based on this premise, if you were to mask the employee's ID because it actually contains his/her social security number, you would have to mask this consistently across these three databases. The backup mechanisms that work at the physical level protect against damage at the file level, such as the accidental deletion of a datafile or the failure of a disk drive. Enterprise Manager's flashback features provide a range of physical and logical data recovery tools as efficient, easy-to-use alternatives to physical and logical backups. When you have finished formatting the column, click OK to return to the Create Masking Definition page. Depending on the service requirements, this activity does not normally cause performance problems. For instance, if you run HR, payroll, and benefits that have an employee ID concept on three separate databases, the concept may be consistent for all of these databases, in that an employee's ID can be selected to retrieve the employee's HR, payroll, or benefits information. You need to add at least one column in the masking definition. Using the Scheduler helps to improve the management and planning of these tasks. Note the references to other sections for supporting information.

Managing Oracle Real Application Clusters databases and instances is similar to managing single-instance databases. If a primary instance fails, Oracle moves the service from the failed instance to a surviving alternate instance. This chapter introduces the concept of database management in the following sections: Masking Sensitive Data for Non-production Use, Monitoring Oracle Real Application Clusters. You can then take the appropriate action required to make a query rewrite. Use the newly created masking definition to initiate masking of the new database. However, if you performing cloning outside of Enterprise Manager, you must initiate masking from Enterprise Manager after cloning is complete. You can use the Database Resource Manager to automatically assign sessions to specific consumer groups by setting up mappings between session attributes and consumer groups. For instance, if you search for social security numbers (SSN) and this yields 100 SSN columns, you could select them all, then click Define Format and Add to import the SSN format for all of them. Each cluster can be comprised of multiple cluster databases, each of which consists of multiple cluster database instances. Use synonyms for the keyword you typed, for example, try “application” instead of “software.”. To search for the list, click the flashlight icon. The run queue length indicates the level of contention for CPU time. Columns that you want to mask as a group must all be from the same table. A cluster database is available as long as one of its instances is available. The Databases page appears. See "Creating a Masking Definition" for more information. Each restore point has a name and creation time. Each version has a unique version number and a synchronization date. It can only specify the types, and the schemas to be included or excluded. Oracle High Availability Database training will teach you how to configure and administer the Oracle Database high availability features contained in Oracle Database, including Clusterware Infrastructure, Automatic Storage Management (ASM), and Real Application Clusters (RAC). These tables contain the mask values that table column or substitute formats will use. For instance, if you click User I/O, the Active Sessions Waiting: User I/O page appears, as shown in Figure 5–3.
